Please upgrade to USB-C PD and 27500 October 23, 2022 Reviewer: Anonymous Person from USA   Please upgrade this product to USB-C PD and 27500. 2 USB-A ports, 2 USB-C ports, fast charge/discharge (PD), and using 27500 batteries would be ideal. Was this review helpful to you?

Excellent Product February 23, 2022 Reviewer: J from WY United States   Bought for battery backup/charging for interchangeable 18650’s across another Nitecore flashlight and headlamp. First experience with Nitecore products. Quality is only matched by Nitecore service which was there when I needed it. Also, their humorous product videos ultimately (no joke) convinced me to try their products in the first place, very synergistic experience from start to finish. Was this review helpful to you?

Dual function product March 5, 2021 Reviewer: Kevin from Colorado   I've had this item for a couple of years now. It had worked great as a regular power bank for all day wrestling tournaments. In addition, it functions as a battery backup for our emergency SRT7 and P12 car flashlights. Really like this product! Was this review helpful to you?
